(Cl. 24-205) My invention aims to provide improvements in foundV that it is most advantageously inserted sliders for use with multiple closure fasteners. when the slider blank has reached the stage In the drawing, which illustrates a preferred shown in Fig. 3 or Fig. 4, at'which point it may be form of my inventlon: placed in the hollow rib just before the ears6 and 5 Figure l is a top plan view of a multiple fasthe sides 3a of the rib are closed in.

My improved slider may be made from any and'easyto manufacture. It has no extra parts 25 suitable material; I' prefer to use brass or some to work loose, and all the surfaces bearing on the similar metal which lends itself readily to' drawfastener elements are smooth, making it easy to ing and bending operations.

A sheet metal slider of the class described lcomprising a pair of similarly shaped plate portions, one of said plate portions overlying the other and being spaced therefrom a predetermined distance to permit thepassage of multiple fastener elements, side.ilanges formed on each plate portion and extending toward the anges on the other,` a hollow riblof U-shaped crosssection formed from the material of said plat-e yportions and connecting said plates together at one end thereof, said rib being curved longitudinally and extending along vthe outside of each plate for a part-'of the length thereof, means providedby said rib to form diverging channels be- Y tween said plates and an independent stiiening member assembled within said hollow rib andconforming'substantially to the shape thereof,

7. A slider of the class described comprising a part shaped to provide a pair of spaced-apart wings, a connecting portion securing said Wings together at one end of the slider and a narrow substantially U-shaped stiiening member formed '0i4 a separate piece of material from said connecting portion `loca/ted entirely within the firstmentioned part adjacentlto'and in line with the connecting portion.
